Politico: “Typically, results aren’t released in (most) states until polls close — and the Associated Press generally will wait until voters are done voting before calling a victory.”
“But Iowa is not a typical election. The caucuses are run by the state party, and not local election officials. With no uniform poll closing time — caucuses started at 7 p.
m. local time, but smaller precincts wrapped up much quicker than big ones — the state GOP started releasing results as soon as they came in.”“Tonight, decision desks relied on the entrance poll, and a few very early caucus results, to confirm what we all knew going into the day — Trump was going to win.”
